MDX parallel period query

After experimenting for some time with MDX parallel period function I could finally write a query which returns two parallel periods as separate rows and not as another column in the same row.

The final query looks like this

SELECT {  [Measures].[Internet Sales Amount] } ON COLUMNS,

NON EMPTY{[Date].[Calendar Weeks].[Calendar Week].ALLMEMBERS} on rows

FROM (

SELECT { ParallelPeriod ([Date].[Calendar Weeks].[Calendar Year]

   , 1 

   , [Date].[Calendar Weeks].[Calendar Week].&[3]&[2012]) , [Date].[Calendar Weeks].[Calendar Week].&[3]&[2012] }

   ON 0 

   FROM [Adventure Works]  )

But interestingly along the way I could figure out another not very idealistic method of achieving the same results, mentioning here just in case it can be used by someone someday

SELECT {  [Measures].[Internet Sales Amount] } ON COLUMNS,

NON EMPTY{[Date].[Calendar Weeks].[Calendar Week].ALLMEMBERS} on rows

FROM (

SELECT ({ Filter( [Date].[Calendar Weeks].ALLMEMBERS - [Date].[Calendar Weeks].[(All)].ALLMEMBERS, Instr( [Date].[Calendar Weeks].currentmember.Properties( 'Member_Caption' ), 'Week 3 ' )  = 1 ) } ,{ [Date].[Calendar Year].&[2011], [Date].[Calendar Year].&[2012] } )

   ON 0 

   FROM [Adventure Works]  )
